many questions about dreams. We dream during the REM (rapid eye movement) stage of sleep. We
have about five periods of REM sleep during the night. The first REM cycle (周期) lasts about 10
minutes. As the night goes on, the REM cycle gets longer. By early morning, the REM cycle can last
up to 90 minutes. Usually, it is in this last REM cycle that we remember our dreams.
Dreams change as people age. People may have several dreams each night. Some are like films
and usually in colour. They come to us over and over again. That may be because the dreamer is
worrying about something and trying to find the answer. Sometimes we wake up with a good feeling
from a dream. But often we can"t remember the dreams clearly.
It is reported that too much dreaming is bad for our health. The more we sleep, the longer we dream.
The mind is hard at work. That is why we may have a long sleep and still feel tired when we wake up? | ( )1. We dream during the REM stage of sleep.
( )2. Children aged eight or nine have the same dreams as people aged thirty.
( )3. All the dreams are usually in colour like films.
( )4. The longer we dream, the better we sleep.
